It depends on you finger skills :). The system can also be programmed to act with "Opel logic" - inverted compared to Renault.
Renault logic is: short press -> windows move automatically; long press -> windows move manually
Opel Logic is: short press -> windows move manually; long press -> windows move automatically
With Opel logic it is easy to move the window few cm only, but it might be annoying for some people to always press long to move automatically.
Just a matter of preference.
